2 Digital Preservation Easy to do as long as you can provide money forever Easy to test claims about repositories as long as you live a long time

3 Demand for a certification process The Preserving Digital Information report of the Task Force on Archiving of Digital Information (Garrett & Waters, 1996) declared: a critical component of digital archiving infrastructure is the existence of a sufficient number of trusted organizations capable of storing, migrating, and providing access to digital collections. a process of certification for digital archives is needed to create an overall climate of trust about the prospects of preserving digital information. The issue of certification, and how to evaluate trust into the future, as opposed to a relatively temporary trust which may be more simply tested, has been a recurring request, repeated in many subsequent studies and workshops.

4 OAIS Reference Model for Open Archival Information System (OAIS) provides an approach Provides vocabulary widely applicable Conformance defined as mandatory responsibilities plus Information Model Does not cover finance etc OAIS approach to digital preservation: covers all types of digitally encoded information provides a way to test whether preservation is successful does not require seeing into the future does require transparency but does not require open access does not cover social and organisational aspects OAIS does provide a good basis for certification

5 Key OAIS Concepts Claiming This is being preserved is untestable Essentially meaningless Except BIT PRESERVATION How can we make it testable? Claim to be able to continue to do something with it Understand/use Need Representation Information Still meaningless Things are too interrelated Representation Information potentially unlimited Designated Community Many other concepts identified Checklist not just blanket term of metadata

6 Information is the important thing What information? Documents Data. Original bits? Look and feel? Behaviour? Performance? Explicit/ Implicit/ Tacit Information: Any type of knowledge that can be exchanged. In an exchange, it is represented by data. Long Term is long enough to be concerned with the impacts of changing technologies, including support for new media and data formats, or with a changing user community. Long Term may extend indefinitely. Ensure that the information to be preserved is Independently Understandable to (and usable by) the Designated Community.

7 Issues of transferring info to Things change: Software future custodians Hardware Environment E.g. Network links to related information People What is common knowledge Organisations and systems Chain of preservation Only as strong as its weakest link How can we ensure that the information trapped in the bits remains understandable despite all these changes? How can current custodian prepare for or even be aware of these changes?

8 RLG/NARA work Part of the OAIS Roadmap Delegated to RLG and NARA to carry forward Plan to bring this come back to CCSDS for standardisation process. Based on OAIS technologies TDR report Finance, Organisational

9 TRAC related work Trusted Digital Repositories: Attributes and Responsibilities from RLG and OCLC Comments on the DRAFT RLG/NARA Audit and Certification Checklist (the "DCC document") nceinputdocuments/ross_mchugh_buetikofer_comments_rlgna RA_AUDIT_ver2.pdf Trustworthy Repositories Audit & Certification: Criteria and Checklist (TRAC) also available from the earlier draft was: RLG/NARA Audit Checklist: TRAC-Nestor-DCC-criteria_mapping.doc: Crosswalk file between TRAC, Nestor and DCC work, which was completed by Robin Dale as a part of the Center for Research Libraries project nceinputdocuments/trac-nestor-dcc-criteria_mapping.doc

10 Other related work English version of the nestor criteria catalogue: OECD Guidelines for the Security of Information Systems and Networks The outcome of the related Chicago meeting is available: Notes from a related meeting in Chicago Jan renceinputdocuments/chicago_meeting.doc DRAMBORA (Digital Repository Audit Method Based on Risk Assessment) - see Joint meeting of Audit and Certification Forum in Berlin 27 Nov 2007 agreed to use RAC as a clearing house after private discussions within the various groups (nestor, DRAMBORA, CRL etc)

11 Repository Audit and Certification Working group Created as CCSDS Birds of a Feather (BoF) group in CCSDS Now an official CCSDS Working Group Open virtual meetings, notes and documents:

12 Background Working Group of CCSDS Charter of WG agreed at meeting January 2007 Goal: Obtain ISO approval of a standard that establishes the criteria that a repository/archive must meet to be designated an ISO Trusted Digital Repository on which a full audit and certification of digital repositories can be based Following route of OAIS CCSDS is the working arm of TC20/SC13 of ISO Based on TRAC document 12

13 RAC Charter Goal 1: Obtain ISO approval of a standard that establishes the criteria that a repository/archive must meet to be designated an ISO Trusted Digital Repository. 1. Review the existing work on audit and certification criteria for digital repositories, such as that from the RLG/NARA working group and the NESTOR project. These two documents are broadly similar, and both are based on the OAIS Reference Model. 2. Prepare a draft (or adopt one of the above documents) and submit to ISO as a Committee Draft to get the ISO process going. 3. Analyse the consistency of those works with the OAIS Reference Model (ISO 14721) and follow on standards such as PAIMAS and the forthcoming PAIS. 4. Review existing audit and certification standards such as ISO 9000 and ISO 27000, and the requirements on such standards for supporting an accreditation and certification programme to obtain guidance on the form of this standard. Neither of these two standards audit the preservation of the encoded information, hence the need for a new standard.

16 Current status An open process with publicly accessible wiki: Weekly online discussions metrics document and other documentation required Notes recorded on wiki with all working documents Agreed as the clearing house for the private discussions of the other groups in this area Major progress at face-to-face meeting in Washington in February 16

17 Current status Now converging fast to agreed documents Audit and Certification of Trustworthy Digital Repositories IN REVIEW PROCESS Requirements for Bodies Providing Audit and Certification of Digital Repositories Almost ready for review 17

18 Issues encountered Science data continuing understandability Authenticity and Information Properties (new OAIS term) Links to ensure consistency with OAIS update Note that the OAIS update is now complete and is in the ISO review process Level of detail of metrics Lessons from others ISO standards e.g. Info. security 18

19 Structure and approach Section A: Organisational Infrastructure Section B: Digital Object Management Section C: Infrastructure and Security Risk Management Metrics and their structure: Statement of requirement Supporting text Examples of Ways the Repository can Demonstrate it is Meeting this Requirement Discussion 19

21 Key Issues (1) How to get from a checklist to an international accreditation/ certification system? The initial auditors Qualification for auditors International set-up

22 Key Issues (2) Evidence short term Evidence long term The real crunch! Risk capture e.g. DRAMBORA tool Quantification The marking system Levels of audit? External review Internal maturity Legal issues

23 The Market Transparency Trustable? certified by whom? to what level? what evidence? with what granularity? for what Designated Community What cost? relevant/sensible? Self-sustaining?

24 Next steps Standards should be approved by Q In early 2010 set up initial audit committee Seek support of funders to do initial audits on a selection of their archives Provide evidence of usefulness of audits to funders Decide pricing structure Ensure consistency of audits results Commitment of audit of repositories of funders Set up national committees Auditor training Start auditing commercial repositories 24
